Disaster Recovery for System Architecture Using Cloud Computing

A System Architecture [SA] plays the leading role in ICT based organization. It covers the entire organization and helps to achieve the mission of organization. As other architectures, it also has set of components and the relationship (connectors) among the components. It has pre-defined life cycle that determines the duration of the system in which it should provide the services continuously. It means system should survive throughout its defined life time. Unfortunately, a system comes across to many hurdles during its life time. In this paper, we propose the reliable approach in recovering from disaster. We analysis the current state of art in disaster recovery and propose the new approach on it. We use cloud computing as a tool in managing the disaster in the system of organization. We analysis our proposed approach with Markov Model. The required attributes for a system to address disaster recovery like availability, survivability, unavailability and downtime are calculated at the end of this paper.
